Abstract
Predmet istraživanja ove doktorske disertacije je modelovanje i analiza uticaja fotonaponskih sistema na elektroenergetski sistem. Naučni doprinosi doktorske disertacije su: • Razvijena je unapređena metodologija za valorizaciju električne energije proizvedene u fotonaponskim elektranama u uslovima slobodnog tržišta i na taj način je omogućena bolja procena ekonomičnosti rada fotonaponskih elektrana u uslovima slobodnog tržišta električne energije. Matematički model za procenu kvantifikatora za valorizaciju električne energije proizvedene u fotonaponskim panelima u uslovima slobodnog tržišta je dat kroz korelacionu analizu tipičnih dijagrama proizvodnje fotonaponskih sistema i dijagrama cene električne energije na tržištu električne energije. • Razvijen je i unapređen stohastički model ekvivalenta mreže i na taj način je omogućeno sagledavanje uticaja disperzovanih fotonaponskih sistema na gubitke aktivne snage u distributivnoj mreži. Ova metodologija omogućava procenu efekata rada kro...vno integrisanih fotonaponskih sistema na smanjenje gubitaka aktivne snage u distributivnoj mreži. • Razvijena je inovirana metodologija za optimizaciju prostorne orijentacije fotonaponskih panela u pogledu profita koji vlasnik fotonaponske elektrane stiče na slobodnom tržištu električne energije.

The subject of investigation of this doctor dissertation is modeling and analysis of the influence of photovoltaic systems upon a power system. The scientific contributions of the doctoral dissertation are: • An advanced methodology of the electrical energy valorization produced by photovoltaic plants under free market conditions has been developed thus obtaining a better estimate of the economy of operation of photovoltaic plants under free market conditions was enabled. Mathematical model for estimating the quantifiers of valorization of electrical energy produced by photovoltaic panels under free market conditions is presented through a correlation analysis of typical diagrams of photovoltaic plants production and diagrams of electrical energy prices at the electrical energy market. • An advanced stochastic model of the network equivalent has been developed thereby it became possible to perceive the influence of dispersed photovoltaic systems upon active power losses in a distributi...on network. This methodology permits estimation of the effects of operation of the building integrated photovoltaic systems on reduction of active power losses in a distribution network. • An innovative methodology for optimization of spatial orientation of photovoltaic panels with respect to the profit gained by the owner of a photovoltaic plant at the free market of electrical energy has been developed.
